One of the more fascinating and fearsome creatures in the world, the scorpion, is even cooler than you might have thought. Research out today confirms these arachnids\u2019 weapons are quite literally laced with metal.<\/p>\n

Scientists at the Smithsonian National Museum of Natural History and others studied more than a dozen species across the scorpion family tree up close. All of the scorpions had various kinds of metal in their pincers and stingers, albeit in unique, sometimes unexpected configurations. These metals play an important role in helping scorpions hunt and defend themselves, the researchers say.<\/p>\n

\u201cThis study highlights that metal enrichment has strongly diversified in relation to how different species have evolved to use their pincers and stingers,\u201d lead author Sam Campbell, who was a pre-doctoral scholar at the Smithsonian at the time of the research\u2019s completion, told Gizmodo.<\/p>\n

Metal arachnids<\/h2>\n

Scorpions are part of the arachnid family, though they split off on their own branch around 435 million years ago. They\u2019re thought to be one of the first animals to have jumped from the sea to land, and they\u2019ve been a rousing success story ever since. Much of this success is due to their body shape, which has remained remarkably consistent to this day. Their grasping pincers and rapidly striking tail, equipped with a stinger that delivers potent venom, can be used to both subdue prey and defend against potential threats.<\/p>\n

Previous studies have shown that some species have metal in their pincers and tails. That said, it wasn\u2019t known if this is a universal feature or whether the composition and location of these metals could differ in relevant ways throughout the large order of scorpions, according to the researchers.<\/p>\n

\u201cTo our knowledge, our study is the first that performs statistical analysis of metal uptake across scorpions while also accounting for phylogenetic relationships,\u201d senior study author Hannah Wood, a research entomologist and curator at the Smithsonian National Museum of Natural History, told Gizmodo. \u201cThis meant we were able to effectively map out how metal enrichment varies between species, and statistically test whether different metals were evolving together, while accounting for shared ancestry.\u201d<\/p>\n

Thanks to the National Museum of Natural History\u2019s extensive collection of preserved samples, the researchers were able to study 18 species representing different broad groups of scorpionkind. They used high\u2011resolution electron microscopy and X\u2011rays to closely examine the scorpions\u2019 pointy appendages.<\/p>\n

They found several similarities and differences between the various scorpions. Zinc was the most prevalent metal found at the very tip of the scorpions\u2019 stingers, for instance, followed by a layer of manganese. The scorpions\u2019 pincers tended to have either zinc or a mix of zinc and iron, though typically only on the cutting edge; that suggests these metals are critical to ensuring the durability of these weapons when hunting prey. And the more zinc a scorpion had in its tail or pincers, the less it had in the other, indicating an evolutionary trade-off, according to Campbell.<\/p>\n
